O. BARTLETT & SNOW COM PANY, 0F CLEVELAND, OHIO, A CORPORATION OF OHIO BARREL H mane AND TREATING MECHANISM Application filed February 11, 1930. Serial No. 427,626.

My invention, relating to barrelhandling and treating mechanism, has speclfic reference to a mechanism by which barrels or like articles are dried preliminary to coating and then further dried to harden such coating before the barrels are filled or otherwise handled.

In the manufacturer of barrels, drums, casts and the like, after the barrel proper has been constructed, it is necessary to test such barrel to determine whether or not there are any flaws in the structure. Such testing is usually accomplished hydraulical- 1y, that is, the barrels filled with water'and subjected to a predetermined pressure. After the barrels have been tested the water is removed therefrom and in the course of this removal and during the testing process the barrels become thoroughly wet, both interiorly and exteriorly. Before the barrels can be painted or coated it is therefore necessary that the interior and exterior thereof be thoroughly dried so that the paint or coating will properly adhere thereto.

After the barrels or like articles have been coated either exteriorly or interiorly they should be thoroughly dried to harden such coating before being further handled in order to preserve such coating from being marred. In the pre-drying of the barrels before coating and the drying of the coating thereof after painting, the usual procedure is to pass such barrels through. elongated drying chambers. It is an object of my in-' vention to provide a barrel handling and treating mechanism which shall effect a predrying and a post-drying in connection with the coating operation, which may be accomplished in a minimum of time, aswell a by an expenditure of a minimum amount of heat.

'When barrels are handled in the manner above described the ultimate cost of the coating operation is in a'great many cases materially enhanced by the necessary expenditure of manual labor in handling the barrels during the various stages of the coating operation. It is an object of my invention to provide a mechanism in which the barrels are transported throughout the several drying chambers without the necessit of employing expensive manual labor to ef feet a transfer of the barrels from one mechanism to another.

Furthermore, a plant which is capable of receiving the Wet barrels after such barrels have been hydraulically tested, drying them preliminary to coating, applying the coating material and then barrels preliminary to their being further handled, should be so designed that a minimum of space is occupied by the entire plant. It is a further object of my invention, to provide a mechanism which shall have all of the above desirable features. Other objects of my invention will appear as the description proceeds.

To the accomplishment of the. foregoing and related ends, said invention, then, consists of the means hereinafter fully described and particularly pointed out in the claims; the annexed drawlngs and the following description setting forth in detail certain mechanism embodying the invention, such disclosed means constituting, however, but OIIIIB of various mechanical forms in which t e In said annexed drawings.

Fig; l is a side elevation of the mechanism comprising my invention; Fig. 2 is a trans verse sectional elevation of the mechanism illustrated in Fig. 1 taken on a plane substantially indicated by the lines22; Fig. 3 is a plan view showing in detail the coat ing apparatus employedat one stage of the apparatus comprising my invention; and Fig. 4 is a detail view to an enlarged scale of a portion ofthe apparatusillustrated in Fig. 1, specifically that at the right hand end of such apparatus.

Referring more specifically to the draw ings, and more especially to Fig. 1, the

mechanism comprising my invention con sists of a pre-drying chamber 1 which is drying such coated substantially rectangular in form having side walls 2, a top 3 and a bottom 4 enclosing a substantially elongated chamber through which barrels 5 may be rolled. The side walls'2 of the pre-drying chamber 1 have longitudinally extending brackets 6 tudinally extending rails 10, here shown in the form of angles having their legs directed upwardly toward the interior of the chamber 1. The pre-drying chamber 1 is suitably mpported by a plurality of legs 11 which are cross-braced by longitudinallyextending members 12 preferably in the form of angles as shown.

Positioned adjacent the receiving end of the pro-drying chamber is a delivery chute 13 which is adapted to convey barrels to be dried from the hydraulic testing machine to the predrying chamber. Positioned in termediately of the skids 13 and the receiving end of the pro-drying chamber 1 is a trip 14 which may control the rate at which the barrels are fed to the drying chamber.v The discharge end of the pre-drying chamber has skids 15 and guide bars 16 associated therewith which receive the barrels from the drying chamber and convey the same onto a painting machine, more or less diagrammatically illustrated at 17. The conveyor chains 7 are mounted on sprockets 18 which. as most clearly shown in Fig. 1, are adj ustable to compensate for elongations in the chain incidental to the wear of its component parts. The chains 7 are supported at the receiving end of the pre-drying chamber by a sprocket 19 which is driven by means of a flexible belt 20 which is in turn driven by a wheel 21 receiving its rotation from a motor 22. The painting machine 17, which specifically forms a part of a copending application, which eventuated into Patent No. 1,871,430, has skids 23 leading therefrom which convey the freshly painted barrels into contact with a feeder device 24. The feeder device 24, which is in the form of a rocker pivotally mounted on a shaft 25, is actuated by a pitman 26, which is terminally mounted on a disk 27 driven through flexible means 28 from a wheel 29 rigidly mounted on the shaft 30.

The drying chambers 31 and 32 are super imposed one on the other directly above the pre-drying chamber 1 and are supported by a plurality of columns 33 and 34. The columns 33 and 34 are interconnected by sills 35 which form the floor supporting means for the drying chamber 31. The chambers 31 and 32 are separated by a longitudinally extending plate 36 which is secured to the columns 33 and 34, through the intermediary of longitudinally disposed angles 37. The columns 33 and 34 have secured thereto angles 38 and 39, and 40 and 41. These paired angles, as shown in Fig. 2, serve as a means of support for a conveyor chain 42, which is of the endless type and which encircles the sprocket wheels 43, 44,45 and 46. The conveyor chain 42 is driven by the sprocket wheel 43. which is mounted similarly to the wheel 21 and which likewise receives its rotation from the motor 22. The sprocket wheels 44, 45 and 46 serve as a guiding means for the conveyor chain 42 and cause such chain to have a portion thereof vertically disposed as diagrammatically illustrated on the right in Fig. 1. The sprocket wheel 46 is mounted on a shaft 47 which is vertically slidably mounted in a block 48 by means of which proper tension in the conveyor chain 42 may be maintained as the component parts thereof are subjected to more or less wear. The sprocket wheel45 is rigidly mounted 011 the shaft 30 and serves as a driving .means for the wheel 29 hercinbefore described.

Oscillatably supported by opposite portions of the conveyor chain 42 are a plurality of barrel conveying trays 49 which spe' cifically form the subject matter of a copending application, which has now matured into Patent No. 1,784,615. The barrel conveying trays 49 have vertically extending side members 50 having stub shafts 52 laterally extending therefrom which are adapted to engage the chains 42. The barrel conveying trays 49 have longitudinally spaced oppositely inclined barrel supporting means 53 which are adapted to engage the chime rings of the barrels and prevent any portion of the body of the freshly painted barrel from coming in contact with any of the conveying mechanism asthe barrel is conveyed through the drying chamber.

When the barrel conveying trays are in the position as indicated by 54 in Fig. 1 the feeder 24 will permit a barrel 5 to roll from the skids 23 onto the supporting means 53. From this position the conveying tray is moved upwardly and as the conveyor chain passes over the sprocket wheel 45 the barrel is longitudinally transported through the drying chamber 31. As the chains 42 encircle the sprocket wheel 43 the trays, with their supported barrels, are transferred to the drying chamber 32 and pass longitudinally therethrough toward the right as viewed in Fig. 1. As the conveying chain 42 encircles the sprocket wheel 44 the barrelconveying trays descend vertically until the barrel strikes the stop 55, which stop rolls the barrels from the conveying trays onto the delivery skids 56 which lead to the tilting device 57. The apparatus for discharging the barrels from their conveying trays during the descent at the right hand end of the apparatus illustrated in Fig. 1 is most clearly illustrated in the enlarged detail view, Fig. 4. It will be noted by referring to this figure that the hereinbefore described tus are feeder arms barrel-supporting trays are suspended between the laterally displaced endless chains and as such trays descend, they meet the knees 55 which project, as most clearly illustrated in this figure,intermediately of the means supporting the barrel on its chime rings, so that the barrel is rolled off on to the skids 56. The tilting device 57 is actuated by a lever 58, which is terminally mounted on a shaft 59 suitably interconnected with, and receiving its motion from, the flexible belt 28. The function of the tilting device 57 is to receive the barrels with their axes in horizontal position and discharge the same therefrom with the axis in a vertical position onto conveyor means, not

shown, which carry the barrels to the point of their destination.

The pre-drying chamber 1 and the drying chambers 31 and 32 are in communication with a vent stack 59 which serves to lead off the hot gases from the several drying chambers and provides a means for circulating the hot air or gases through the several chambers, which is essential to the proper drying of the barrels.

The apparatus generally indicated at 17 in Fig. 1 which is employed for the purpose of coating the barrels is most clearly illustrated in Fig. 3. Referring now more specifically to this figure, it will be noted that the apparatus illustrated herein is substantially the same apparatus forming the subject matter of my copending application Serial No. 427,627, filed Feb. 11, 1930. The main frame 61 of the apparatus has slidably supported thereon two cross heads 62 and 63 which are movable toward and away from each other upon rotation of the shaft 64 as is most clearly illustrated in my copending application. The cross heads 62 and 63 have secured thereto paired conical rollers 65 and 66 respectively, which are mounted on the ends of stub shafts rotated through suitable driving means by a motor such as 67. The coniform rollers 65 and 66 may be moved toward and away from each other as indicated by the dotted line positions in this figure upon relative movement of the cross heads 62 and 63, so that the apparatus may be adapted to accommodate barrels, or like cylindrical articles, of varying lengths. Associated with the feeding end of the appara- 68 and positioned intermediately of the cross heads 62 and 63 are discharge arms 69 having rotatably mounted on their terminals conical rollers such as 70 which, upon rotation of the shaft 71 on which the arms 69 are secured, will move into engagement with the chime rings of the barrels and move the same from the coating machine. Actuation of the shaft 71 and the shaft 72, the latter shaft being one to which the feeder arms 68 are secured is effected by a pedal 73, which will be operated by the painting operator as soon as the barrel positioned on the machine has been coated and ready to be discharged to make room for the next succeeding barrel.

The operation of the barrel-conveying means in the pre-drying chamber, i.e., the endless chains and the transversely extending shafts 8 thereof, will preferably be intergeared with the other mechanism forming the subject matter of my invention, so that the barrels will move through the predrying chamber synchronously with their movement through the other parts of the apparatus, so that the barrels, or like cylindrical articles, will be fed at an even rate and at equally spaced intervalsthroughout the entire drying coating and handling equipment. V

The vertical displacement .of the drying chambers 31 and 32, as shown at 60 in Fig. 1, is mainly for the purposes of making the entire drying mechanism of a more compact structure, thereby decreasing the head room required at this end of the installation, and also to conserve the heat necessary to effect a proper drying of the barrels in the several chambers.

In connection with the above description it will be noted that a number of the parts are more or less diagrammatically illustrated inasmuch as the specific construction of the various elements is not essential to the principles of my invention. The description of the various parts is sufiicient for those acquainted with the art so that a detail de scription of the various parts "is believed unnecessary for a full comprehension of my invention.

It will be seen that the arrangement of the various parts of my mechanism presents advantages which are exceptionally beneficial from the standpoint of the ease with which the outlined operations are accomplished, as well as the reduction in cost of the barrel coating process. The arrangement of the drying chambers, superimposed one on another, prevents a loss of heat, due to radiation, which has heretofore been one of the chief items of expense of the outlined process. The general arrangement of the various parts, specifically the position of the painting machine with respect to the discharge end of the pre-drying chamber and the vertically disposed portion of the conveyor chain for the drying chambers permits the barrels to be handled with a minimum amount of manual labor and also goes to make the general arrangement of the entire plant desirable from the standpoint of the and the cost of producing the- 'same.

Other modes of applying the principle of my invention may be employed instead of the one explained,- regards the mechanism herein disclosed,

quality of the finished productprovided the means stated by any of the following claims or the equivalent of such stated means be employed.

I therefore particularly point out and distinctly claim asmy invention 1. In an apparatus of the character described, the combination of a horizontal extending pro-drying chamber, with a coating chamber and a post drying chamber, of a cradle conveyor for carrying barrels from said coating chamber and through said said post drying chamber, said post drying chamber being super-posed upon said predrying chamber, and comprising an elongated closed conduit having a horizontal partition extending therein, the inlet and outlet of said conduit facing downwardly and lying below the floor adjacent the inlet of the post-drying chamber, said conveyor extending vertically adjacent said coating chamber from a point therebelow. whereby coated barrels may be received from said coating chamber and then carried upwardly and into said post drying chamber.
